CONCRETE RAILROAD-TIE.

Liesbet.

Application filed September $38, 1914.

To all fr0/wm t may concern Be it known that I, VILLIE ELMER NAR` REN, a citizen of the United States, residing at Test York, in the county of Crawford and State of Illinois, have invented certain new and useful Improvements in Concrete Railroad-Ties; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in railroad ties and has for its main object to provide an extremely simple filler for cement ties, which may be constructed of a single I beam.

A further object is to provide combined rail receiving and reinforcing plates on the opposite ends of the filler, and two pairs of longitudinally and transversely spaced upright bolts for securing the rails and plates in position and for simultaneously bracing the I beams against twisting.

In connection with the upright bolts, a still further object of the invention is to provide novel means for reinforcing the portions of the I beam through which the lower ends of said bolts pass.

With the above and other objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is a side elevation, partly in sec tion, showing the application of a tie, constructed in accordance with my invention to use; Fig. f2 is a top plan view of the parts seen in Fig. 1; Figs. 3 and l are vertical transverse sections as seen on the lines 3--3 and Ll--4 of Fig. 1; and Fig. 5 is a side elevation, partly in section, showing a slightly different form of construction.

In the accompanying drawings from Figs. 1 to 4, a pair of rails R are shown, whose bases rest upon combined reinforcing and rail receiving plates 1, said plates contacting the upper horizontal flanges 2 of a transverse I beam 3, whose lower flanges 4 are provided with two pairs of depending lugs or bosses 5. It will be noted that a pair of bosses 5 depends from each end portion of the I beam 3, and that said bosses, together with the upper and lower flanges of said beams, and the plates 1 receive upright clamping bolts 6, which are spaced Specification of Letters Eatent.

Serial No. 863,903.

both transversely and longitudinally, whereby said bolts straddle the bases of the rails lt, and the upright webs 7 of the beams 3.

Slidably mounted upon the free upper ends of the bolts 6, are rail clamping jaws 8 having tongues 9, which overlie the bases of the rails R, nuts 10 being threaded upon the extreme upper ends of said bolts and being provided for forcing the jaws 8 into contact with said bases.

By positioning the bolts G, as above described and as illustrated in the drawings, the upper and lower flanges 2 and ai, of the VI beams 3, are positively held in xed relation or, in other words, twisting of the I beam is effectively prevented, since said bolts are located on opposite sides of the web 7 and are spaced considerable distances therefrom. 'J'.his is an extremely important feature of the invention, and would operate to equal advantage with the plates 1, and the bosses 5 eliminated, although these elements are preferably applied for the pur pose of reinforcing the upper and lower flanges of the beams 3.

The entire device, as above described, would, in some cases, operate without the provision of a protector, but the same is preferably entirely embedded in plastic material 11, with `the exception of the upper faces of the plates 1 which lie flush with the top of the protector 11, and the lower ends of the reinforcing bosses 5, which lie Hush with the lower side of the said protector.

In Fig. 5, an I beam is shown having a pair of reinforcing plates 1 formed integrally with the opposite end portions of its upper flanges, the lower flanges of said beam being provided with bosses 5 through which, the upper and lower flanges, and the plates 1', clamping and bracing bolts 6, pass, said bolts carrying rail clamping means 8 upon their upper ends, said means being identical with the form previously described.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that an extremely simple construction has been provided for carrying out the objects of the invention, yet that the efliciency of the device will not be impaired by such simplicity.

I claim:

1. A railroad tie comprising an I beam to be positioned transversely beneath a pair of longitudinally spaced rails, two pairs of longitudinally and transversely spaced bolts, rising through the upper and lower flanges of the I beam and straddling the web thereof, and rail clamping means slidable on the upper ends of said bolts and nuts on said ends bearing against said clamping means, a pair of said bolts being located at each end of the beam and being designed to straddle the bases of the rails.

2. A railroad tie comprising an I beam, to be positioned transversely beneath a pair of longitudinally spaced rails, two pairs of longitudinally and transversely spaced bolts rising through the upper and lower flanges of said I beam, reinforcing bosses depending from the lower flange of said beam and likewise receiving said bolts, and clamping means on the upper ends of said bolts, a pair of the latter being provided at each end of the beam and being designed t0 straddle the bases of the rails.

3. A railroad tie comprising an I beam, two pairs of longitudinally and transversely spaced bosses depending from the lower side thereof at its opposite ends, two pairs of bolts rising through said bosses and through the upper and lower flanges of the said I beam, said bolts straddling the web of said beam and being designed to straddle the bases of the rails, rail clamping means on the upper ends of the bolts, and a plastic protector inclosing the major part of the I beam.

4. A railroad tie comprising an I beam,

two pairs of longitudinally and transversely spaced bosses depending from the lower side thereof, at its opposite ends, combined reinforcing and rail receiving plates upon the upper side of said beam at its opposite ends, combined clamping and bracing bolts, rising through the bosses, the upper and lower flanges of the beam and through the plates, and rail clamping means on the upper ends of said bolts.

5. A railroad tie comprising an I beam, two pairs of longitudinally and transversely spaced bosses depending from the lower side thereof, at its opposite ends, combined reinforcing and rail receiving plates upon the upper side of said beam at its opposite ends, combined clamping and bracing bolts, rising through the bosses, the upper and lower flanges of the beam and through the plates, rail clamping means on the upper ends of said bolts, and a plastic covering inolosing the entire beam, with the exception of the plates and the bosses carried thereby, the former lying flush with the top of the covering and the latter lying flush with the bottom thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
